Behaviour of Ag-110m and Ru-103,Ru-106 in the environment after the Chernobyl accident
The contamination from radionuclides originated from the Chernobyl accident in the processes of copper and noble metal production from the ore of open cut mining was investigated. Presence of Ag-110m and Ru-103,Ru-106 in copper roast and subsequent products was found having constant ratio (110)mAg/Ru-106 (4.0 +/- 1-2) x 10(-2). A model of the transport mechanism of radionuclides as well as the value of contamination were considered. (C) 1998 Elsevier Science Ltd. All rights reserved.
